摘　　要：制备了改性PSF超滤膜,研究了原膜、改性膜分别与混凝工艺组合处理赣江微污染水源水的处理效果。研究表明,组合工艺处理浊度时,两膜的处理效果都比较明显,PAC的加入量对其影响较小。对UV_（254）、氨氮进行处理时,改性膜的处理效果均比原膜好。加入40 mg/L的PAC时,两膜对UV_（254）的去除率达最大值,其中原膜为39.52%,改性膜为58.73%。在PAC的投入量由10 mg/L增至30 mg/L的过程中,两膜对氨氮的去除率均呈增长趋势,其中原膜由13.23%增至23.68%,改性膜由17.57%增至39.42%,继而增大PAC的加入量,去除效果无明显变化。PAC的加入量在10～30 mg/L时,原膜的极限超滤时间维持在70 min以上,改性膜的极限超滤时间维持在150 min以上。综合考虑出水水质和经济成本的影响,采用组合工艺处理赣江微污染水源水时PAC的加入量宜在30～40 mg/L范围内。Preparation of the modified PSF ultrafiltration membrane and to study combination treatment with coagulation process of Ganjiang micro-polluted raw water treatment effect is found when combined process turbidity processed membrane and treatment effect modification of the original membrane are more desirable, PAC dosage of turbidity removal rates have little impact. When UV_（254）, ammonia processed, modified the treatment effect is good than the original membrane. When the PAC dosage of 40 mg/L the original membrane on UV_（254） removal rate is 39.52%, the highest removal efficiency of the modified membrane is 58.73%; When the PAC dosage 10 mg/L is increased to 30 mg/L, original membrane of ammonia nitrogen removal rate increased to 23.68% from the 13.23%, modified membrane of ammonia nitrogen removal rate increased from 17.57% to the 39.42%,continuous increase the dosage of PAC does not show obvious removal effect. When the dosage of PAC in the 10～30 mg/L, the original time limit of the ultrafiltration membrane is maintained at more than 70 min, modified ultrafiltration membrane time limit be maintained at more than 150 min.Considering the water quality and the economic costs, it can be determined that the suitable dosage of PAC in combined process for Ganjiang slightly polluted water was between 30～40 mg/L.
